Abstract

Objectives: To assess the use of bimaxillary splint-supported Forsus Fatigue Resistant Device (FFRD) with and without miniscrew anchorage in treatment of skeletal Class II growing patients.
Materials and Methods: The sample comprised 26 skeletal Class II female patients. They were randomly distributed into two groups: 13 patients (11.87 + 0.94 years) received splint-supported Forsus without miniscrews (SSF group) and 13 patients (12.02 + 1.03 years) received splint-supported Forsus with miniscrews (SSFM group). Three-dimensional CBCT analysis was done, and the obtained data were statistically evaluated.
Results: Both groups showed significant skeletal headgear effect with reduction of SNA angle (-0.88° + 0.51° and -1.15° + 0.56°) in SSF and SSFM groups respectively. Lower incisors showed significant less proclination (5.1°+2.23°) and protrusion (0.8 mm ± 0.55 mm) in the SSFM group.
Conclusions: The splint-supported Forsus FRD was effective in treatment of skeletal Class II malocclusion with dentoalveolar changes and maxillary skeletal headgear effect. The use of miniscrews with the splints resulted in less lower incisors proclination.
